<p>Cultivated potato is a drought-, salinity-, and frost-sensitive species. The transgenic approach is one of the methods used to mitigate abiotic stress. The utility of transgenic potatoes that have abiotic stress tolerance should be judged from their yield under stress conditions. In order to establish transgenic potato lines with the AtDREB1A gene that could be used in practical applications, we screened candidate lines in a growth room with growth profiles under non-stress conditions rather than the expression level of transgene. After identifying better transgenic lines (D163 and D164), yield of those lines under stress conditions was evaluated in the special netted-house. Although the yield was lower than the yield under non-stress conditions, two selected transgenic lines were able to maintain their yield under high saline conditions (EC > 10 mS/cm). In this study, fertilizer was not added beyond what was already contained in the soil mix in order to evaluate the yield of the transgenic lines under saline conditions in as simple a manner as possible. In future studies, it will be necessary to evaluate their yield in a farming context in an isolated field after assessing the environmental biosafety of these transgenic potato lines.</p>
